COG R&D GOAL

COG’s R&D Goal is to assist participating Members to achieve excellence in the safety, reliability and economic performance of their CANDU stations worldwide by initiating and managing jointly funded R&D

COG R&Daddresses current and emerging operating issues to support the safe, reliable and economic operation of CANDU reactors.is sponsored by Ontario Power Generation, Bruce Power LP, New Brunswick Power Nuclear, SNN-SA (Romania), KHNP (Korea) and by Atomic Energy of Canada Limited.Deals mainly with CANDU-specific problems.

R&D Program Overview

Chemistry, Materials & Components addresses a diverse range of CANDU reactor operating and maintenance issues that impact the economics and reliability of a station and may shorten its operating life: chemistry control regimes; material aging effects; valves; cables; sealants; lubricants and other organically based materials.

Fuel Channels addresses the issue of fuel channel life cycle management through technical support for fitness for service (CSA N285.8).refining the models to predict deformation, corrosion and deuterium ingress.

Safety and Licensing addresses issues relating to the safety design basis and safe operating envelope of existing facilities focuses on the resolution of outstanding generic safety and licensing issues

(TC Directed) COG-11-4049 Plant Assessment of Indirect Inspection Techniques for Detection of Coating Defects on Buried Piping

Indirect inspection techniques, which are being successfully used in the oil and gas pipeline industry, are facing challenges in nuclear power plants. In this project, selected over the line survey techniques were evaluated in a plant test. This document reports and discusses the findings of the testing performed in AECL Laboratories at Chalk River, providing some valuable insights into the capabilities and limitations of the indirect inspection techniques for plant buried piping integrity management programmes.

Fuel Channel Program

The Fuel Channel R&D program in place for 30 years.

The CSA Standard for Fuel Channel Life Assessment was developed by the R&D program and the focus of the R&D program is to primarily provide technical justification that address issues in the CSA Standard.

The Fuel Channel Program supports JPs on:

Confirmatory Critical Heat Flux and Post-Dryout Experiments Using the Modified 37-Element Fuel Simulation in Water

experiments were performed to confirm the results of the tests that were originally performed in 2008 using the modified bundle that exhibited improved CHF performance that could be beneficial in increasing safety margins in aging reactors.

Modified 37 Element Fuel Bundle – Background/Heat Distribution

Temperature maps from recent tests of Reference (left) and Modified (below) bundles at left demonstrate impact of design change•Same boundary conditions

Reduced centre element diameter results in:•Reduced temperature in the centre of the bundle•Reduced maximum temperature•More even radial heat distribution

WP 30478 – Thermal Effect Benchmarks addresses the need to further refine thermal effect endpoints for fish species at risk to permit accurate risk assessment evaluations by life stage for these species. The objective of the study was to develop updated thermal preferences and tolerances for round and lake whitefish eggs. Earlier studies on developing thermal tolerances for round whitefish are over 30 years old, and were not conducted with ambient lake temperatures. Present studies were conducted in a hatchery specially design for thermal inputs which were computer controlled (see next slide). Egg incubation studies focused on the temperature effects on embryo development for both species.This project has generated considerable positive interest in several government departments, both federal and provincial. A paper on interim results given at the recent American Fish Society conference was well received.
